INTERNATIONAL ELECTROTECHNICAL COMMISSION

DIMENSIONS OF HALF POT-CORES MADE OF FERRITE

FOR INDUCTIVE PROXIMITY SWITCHES

FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees) The object of the IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields To

this end and in addition to other activities, IEC publishes International Standards Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)“) Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work International, governmental and

non-governmental organizations liaising with the IEC also participate in this preparation IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter

5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with an IEC Publication

6) All users should ensure that they have the latest edition of this publication

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications

8) Attention is drawn to the Normative references cited in this publication Use of the referenced publications is

indispensable for the correct application of this publication

9) Attention is drawn to the possibility that some of the elements of this IEC publication may be the subject of

patent rights IEC shall not be held responsible for identifying any or all such patent rights

International Standard IEC 62323 has been prepared by IEC technical committee 51:

Magnetic components and ferrite materials

This standard cancels and replaces IEC/PAS 62323 published in 2002 This first edition

constitutes a technical revision

The text of this standard is based on the following documents:

FDIS Report on voting 51/817/FDIS 51/825/RVD

Full information on the voting for the approval of this standard can be found in the report on

voting indicated in the above table

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2

62323  IEC:2005(E) – 3 –

The committee has decided that the contents of this publication will remain unchanged until

the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in

the data related to the specific publication At this date, the publication will be

• reconfirmed;

• withdrawn;

• replaced by a revised edition, or

• amended

A bilingual version of this publication may be issued at a later date

DIMENSIONS OF HALF POT-CORES MADE OF FERRITE

FOR INDUCTIVE PROXIMITY SWITCHES

1 Scope

This International Standard lays down the important dimensions for the mechanical

interchangeability of a preferred half pot-core series of ferrite, intended to be used in

inductive proximity switches

2 Normative references

The following referenced documents are indispensable for the applicatiuon of this document

NOTE 1 The core may have up to two slots in order to realize the wire connection feed-through holes

NOTE 2 A centre hole (H) is allowable

NOTE 3 Chamfers are allowable as long as they do not limit the winding space

4 Requirements

In order to avoid damage to the coils and their interconnection wires, the cores shall be

delivered without burrs Flashes according to 3.3 of IEC 60424-1 shall not be present either

on the winding area limiting surfaces including edges or on the wire connection feed-through

holes

5 Marking

A manufacturer specific marking is mandatory from PS 7,35 and larger, preferably on the

bottom of the core
